Every day in the UK over 150 women will be given the devastating news that they have breast cancer. This is the start of a long journey of treatments that usually involves surgery to remove the tumour – most likely followed by radiotherapy to the breast or chest wall. What many people might not realise though is that radiographers often use small permanent black ink tattoos in order to position a patient underneath the radiotherapy machine. These small tattoos are placed on the patient’s breast bone, and at points across the thorax. While these tattoos are small (about one to two millimetres in diameter), they are permanent. The patient will have these tattoos for the rest of their lives, long after any surgical scars have faded.
But new technology, called surface guided radiotherapy (SGRT), uses three dimensional imaging to help radiographers position patients, avoiding the need for tattoos. A 3D image is first taken as part of the planning for treatment. This image is then used prior to each radiotherapy session to ensure the patient is in the correct position. This also means that patients can be positioned underneath the radiotherapy machine without using tattoos. As with many new technologies though, it can be costly.
In the 1980s it was common for patients having radiotherapy for breast cancer to be marked with semi-permanent ink. But these could rub off onto the patient’s clothes or when showering. If semi-permanent marks fade or need reapplying, there’s a potential for the marks to be redrawn differently, which could affect the accuracy of radiotherapy. Concerns over these semi-permanent marks disappearing before the patient had completed the full course of radiotherapy led to the gradual use of permanent tattoos as standard. For most patients with breast cancer, around three permanent tattoos are currently used for treatment on average.
Breast Cancer Survivors Show Strength With Tattoos
However, a study of over 300 women randomised to have either permanent tattoos or semi-permanent marks, no differences in accuracy was found between the skin marking methods. In 2018, when I was diagnosed with breast cancer and needed to undergo radiotherapy myself, I was keen to avoid having permanent tattoos. I opted to have a semi-permanent ink mark on my breast bone that was covered with a water-proof dressing. Semi-permanent marks have the advantage of disappearing once treatment is finished – but again, their disadvantage is that they could wash off, which means patients need to be careful when showering during the three to four weeks of treatment. Many patients are also rarely given an option to have semi-permanent marks. The default is to tattoo patients.
Other skin marking methods have been tried, including the use of ultraviolet tattoos that would only be visible in black light. These aren’t without their disadvantages, as a recent trial found. Researchers discovered UV tattoos were difficult to see on the two patients with sub-Saharan skin tones. UV Tattoos might also be visible under black lighting conditions in bars or restaurants, making it an undesirable option for many.
Surface Guided RadioTherapy methods have been shown to have better positioning accuracy than permanent tattoos. One study found permanent tattoos required positioning corrections in 28% of cases, compared with just 7.7% of cases when Surface Guided RadioTherapy was used. Surface Guided RadioTherapy also reduced the time required for positioning on average of one minute and seven seconds per patient. Over the course of a day, this small time savings could equate to an additional four patients per radiotherapy machine being able to be treated. This is significant, given radiotherapy resources are limited.
Can Tattoos Cause Skin Cancer?
Of most concern, though, is the distress that tattoos can have on some women during what can be an already distressing treatment journey. In an online survey of breast cancer patients, 78% said they would choose a treatment where they didn’t have to have skin marks or tattoos, even if that meant they had to travel farther to have radiotherapy.
As part of our ongoing research, we asked women who had been through radiotherapy about their thoughts on permanent tattoos. Women reported a range of different experiences, emotions and knowledge about the use of tattoos. A few women didn’t mind having the tattoos. But others often experienced lack of choice, disempowerment, and the realisation of the enormity of the cancer, given it required a permanent mark.
For me, having to have a permanent tattoo visible in the middle of my chest was not about having a permanent reminder of the cancer. It was more about being able to go back to wearing the clothes I have always worn, about going back to the gym, about sun bathing on holiday, about trips to the spa without having to worry about a radiotherapy tattoo being visible to others for questions. Sometimes, you don’t want to have to explain to inquisitive people why you have a black dot on your chest, you just want to get on with living.

Surface guided radiotherapy is a non-invasive technology that allows accurate positioning of patients for breast cancer radiotherapy that leaves no permanent marker of cancer treatment. This will give many patients the opportunity to get on with living once treatment has finished.It’s a tiny hardship amongst something far scarier, but for generations large numbers of cancer patients have received miniature tattoos during treatment.
The tattoos are used to align patients' bodies with radiotherapy machines, so the powerful treatment can be delivered precisely, day after day.
They also remain long after the cancer has gone, as permanent reminders of what people have endured, sometimes stretching and spreading over time.

The Alfred hospital in Melbourne says it has become one of only a handful of centres worldwide to deliver radiation without any skin marks, instead using surface guided technology to find the correct position.
David Waters has two faded dots on each side of his chest and back. He received the tattoos when he was treated for Hodgkin’s lymphoma almost four decades ago.
“In my days at St Vincent’s Hospital in Darlinghurst Sydney, they put the tattoos on and then marked the rest using marking pens, ” he said.

Recently the 59-year-old executive with World Vision Australia was again diagnosed with cancer, likely as a result of the “scattergun” radiation treatment he received when he was a young man.
This time the cancer was in his throat and tongue. He had to have his larynx removed, meaning he can no longer speak and breathes through a stoma in his throat. He finds other ways to communicate now, including using a text to voice app.
Yet despite all he has been through, he says he tries to see his tattoos as a gift, not a bad memory.

“I hate how my cancers have physically impacted me, however, I know that in terms of resilience and self-awareness, I am very lucky, ” Mr Waters said.
Not everyone feels the same way. Others say that the tattoos are an unwelcome reminder of their cancer, that they bleed underneath the skin and can be difficult to cover up, especially for breast cancer patients.
Such complaints were behind the The Alfred’s decision to phase out tattoos and other skin markings. Since last year teams at the hospital and a satellite centre in Traralgon in regional Victoria have been setting up breast cancer patients without any skin markings, and say it doesn't have any negative impact on the accuracy of the treatment.

Acting deputy radiation therapy manager Catherine Russell said The Alfred decided to start with breast cancer patients because it felt they were most impacted by the tattoos.
“For breast patients in particular, it is very common to need up to four or five tattoos in the chest region. One is located in the middle of the sternum, which is very hard to hide, ” Ms Russell said.
The most common alternative to tattoos involves marking patients with permanent pens and trying to get them to preserve the marks with clear surgical tape.

“We would accompany that with instructions about how to preserve the lines, such as using baby powder to help stop them running off and patting them off after showering instead of rubbing, ” Ms Russell said.
Associate Professor Dion Forstner from the Royal Australian and New Zealand College of Radiologists said tattoos were still the preferred method of positioning and, despite the cosmetic issues, worked very well.
“There is a prick of the skin with a needle and then some Indian ink is dropped onto that little hole, ” Professor Forstner said.

Jacqui Carton received seven of the pinpoint tattoos in her breast area when receiving treatment for cancer at the Sunshine Hospital Radiation Therapy Centre in 2015.
She said although the dots no longer have any negative association for her, removing the tattoos would mean one less thing patients would have to deal with.
“It was my first tattoo so I was completely petrified when I got them, ” she said. “In the end it just felt like another needle.”We are proud to share that one of our family of advanced skin care clinics is now offering a free radiotherapy tattoo removal service to support breast cancer patients.
